Abstract
The invention is directed to device and a method to establish a Joint connection (17) with a sleeve (12) comprising at least one susceptor (13, 14) by inductive heating by a welding device (1).
Claims25
Sleeve (12) comprising a carrier (9) made out of injection molded thermoplastic material and at least one susceptor (13, 14) being at least partially embedded in the carrier (9).
The sleeve (12) according to one of the previous claims, characterized in that the at least one susceptor (13, 14) is ring-shaped.
The sleeve (12) according to one of the previous claims, characterized in that the at least one susceptor (13, 14) consists out of perforated metal sheet with openings (25).
The sleeve (12) according to one of the previous claims, characterized in that the at least one susceptor (13, 14) is made out of a non-corrosive material.
The sleeve (12) according to one of the previous claims, characterized in that the at least one susceptor (13, 14) is arranged flush to the contact surface (18).
The sleeve (12) according to one of the previous claims, characterized in that the sleeve (12) comprises a tag carrying information about the characteristics of the at least one embedded susceptor (13, 14).
The sleeve (12) according to one of the previous claims, characterized in that the sleeve (12) comprises means to determine the temperature of the at least one susceptor (13, 14).
Welding device (1) to establish a joint connection by a sleeve (12) according to one of the previous claims, characterized by a coil (3) to generate an electromagnetic field field, a HF-generator to drive the coil (3), a control means interconnected to the HF-generator and/or the coil (3) to control a welding process and an input means (22, 23) to provide the control means with information about the characteristics of a susceptor embedded in the sleeve (12).
